Abstract: A vehicular trailer angle detection system includes a rear camera, a left-side camera, a right-side camera and a control having an image processor. With a trailer hitched at a vehicle, and while the vehicle is driven in a forward direction and towing the trailer, image data is captured by at least one of the cameras. The vehicular trailer angle detection system determines an expected location of the portion of the trailer based on provided vehicle-trailer parameters as the vehicle is driven forward and towing the trailer. The vehicular trailer angle detection system determines an actual location of the portion of the trailer via processing of captured image data as the vehicle is driven forward and towing the trailer. Responsive to an offset between the determined actual location of the portion of the trailer and the determined expected location, the vehicular trailer angle detection system accommodates the offset.

Abstract: A dynamic calibration method for calibrating a trailer angle detection system of a vehicle towing a trailer includes providing cameras configured to be disposed at the vehicle so as to have respective fields of view. Image data captured by at least some of the cameras is processed as the vehicle is driven forwardly and towing the trailer. A location of a portion of the trailer is determined via processing of captured image data. Responsive at least in part to processing of captured image data, a plurality of trailer parameters and vehicle-trailer interface parameters are determined. The plurality of trailer parameters and vehicle-trailer interface parameters are determined while the vehicle is driven forwardly and towing the trailer. The trailer angle detection system of the vehicle is calibrated responsive to determination that the trailer portion is not where the system expects it to be when the vehicle is traveling straight forward.

Abstract: A method for dynamically calibrating a vehicular trailer angle detection system includes providing at least a rear camera at a rear portion of the vehicle. A trailer is hitched at the vehicle and the vehicle is driven forward while towing the trailer. The control determines an expected location of a portion of the trailer based on provided vehicle-trailer parameters as the vehicle is driven forward and towing the trailer. An actual location of the portion of the trailer is determined via processing at the control of captured image data as the equipped vehicle is driven forward and towing the trailer. The vehicular trailer angle detection system is calibrated responsive to determination, via processing at the control of captured image data as the equipped vehicle is driven forward and towing the trailer, that the determined actual location of the portion of the trailer is not at the determined expected location.

Abstract: A method for assisting a driver of a vehicle towing a trailer includes providing a plurality of cameras and processing image data captured by the cameras while the vehicle is towing the trailer. Responsive to processing of captured image data, images are generated for display at a video display screen to provide a top view of the vehicle towing the trailer to the driver to assist maneuvering the vehicle towing the trailer. A dynamic vehicle and trailer icon is generated and displayed at the video display screen along with display of the top view of the vehicle towing the trailer. The dynamic vehicle and trailer icon comprises a top view representation of the vehicle and the trailer with at least one projected path for the vehicle towing the trailer so the driver can readily determine where the trailer will travel when the driver turns a steering wheel of the vehicle.

Abstract: A vehicular imaging system includes a camera with an imaging sensor. A first spectral filter is disposed at each pixel of a first set of photosensing pixels, a second spectral filter is disposed at each pixel of a second set of photosensing pixels, and each pixel of a third set of photosensing pixels senses at least near infrared radiation. Image data provided to the image processor includes output of the first set of photosensing pixels, output of the second set of photosensing pixels and output of the third set of photosensing pixels. The outputs of the photosensing pixels of the first and second sets of photosensing pixels are processed for a color camera function of the vehicle. The output of the photosensing pixels of the third set of photosensing pixels is processed for a night vision function of the vehicle.

Abstract: A method for assisting a driver of a vehicle towing a trailer includes providing a rear backup camera at a rear portion of the vehicle. A trailer having a trailer tow bar is attached to the trailer hitch of the vehicle. The vehicle is driven while towing the trailer and image data is captured via the rear backup camera and provided to a control at the vehicle. The image data captured while the vehicle is towing the trailer is processed at the control to determine an angle of the trailer tow bar relative to the vehicle. Responsive to determining the angle of the trailer tow bar relative to the vehicle, a degree of sway of the trailer relative to the vehicle is determined. Responsive to determination that the degree of sway is greater than a threshold degree of sway, an output is generated via the control.

Abstract: An imaging system suitable for use in a vehicle includes an imaging sensor having a two-dimensional array of photosensing pixels that includes at least one sub-array having a first photosensing pixel, a second photosensing pixel, a third photosensing pixel and a fourth photosensing pixel. Spectral filtering is disposed at the photosensing pixels whereby the first photosensing pixel primarily senses red visible light, the second photosensing primarily senses blue visible light, the third photosensing primarily senses green visible light and the fourth photosensing primarily senses infrared radiation. The imaging sensor is disposed at a vehicle and has a field of view external of the vehicle. An image processor is operable for processing image data captured by the imaging sensor. The image data includes outputs of the first, second, third and fourth photosensing pixels. The processing of image data by the image processor may include de-mosaicing that reduces infrared color wash-out.
